[HECnet] Attaching to hecnet

There are additional limitations to phase III nodes in a phase IV network. Phase III nodes do not have any idea of areas, and all node numbers must be below 256. (In short, phase III nodes use a single byte for node addresses.) So, a phase III node can only talk with other nodes within the same area, and only if those nodes have low node numbers. For some applications, PMR can make phase III nodes be able to talk with machines in other areas, or with high numbers. I have no idea about the rest... Johnny Kari Uusim ki wrote: Yes, indeed. It wasn't even meant to work. Here's an excerpt from the DECnet (Phase IV) manual: DECnet supports a variety of types of nodes developed during different phases of DNA implementation. Phase II, III, and IV nodes and DECnet/OSI nodes can all exist on a network. There are con guration restrictions in such a mixed network; one major restriction is that only nodes running adjacent phases can communicate directly, as shown in the following list: Phase II Phase II Phase II Phase III Phase III Phase III Phase III Phase IV Phase IV Phase IV Phase IV DECnet/OSI DECnet/OSI DECnet/OSI Later there is mentioned that a Phase III node can exist in an Phase IV area as an end node. It can communicate with a Phase V node through the Phase IV area. I don't have personal experience with DECnet Phase III.

But poor man's routing will work with a phase IV node in between. Functionality of course is limited by the phase III host :-) But you're absolutely right that very few people will have a phase III system, RT-11 being the most likely candidate? I've seen the bridge program, but am not sure how to make the .conf file work. Is it possible to use DECnet address 1.1010 to try and make this work?

H Vlems wrote: DECnet phase IV nodes are backwards compatible with phase III. Yes. But the question here was if phase V will interoperate with phase III. I don't know the answer to that one, but on the other hand, I don't think anyone around is running phase III anyway. There are no restrictions in functionality between phase IV nodes and phase V as seen by the unpriviledged user. Area routing may be an issue on Alpha, and of course ncl is more of a pain to remember than ncp ;-) True, as far as that goes. However, I am not sure that a phase V node can operate as a phase IV area router. Someone else pointed out that although DEC claimed that alphas could not be area routers, that information is incorrect, and you can just tell an Alpha VMS phase IV node to be an area router, if you want to. However, DECnet+ is phase V, and all bets are off. :-) And yes, not only are the NCL commands more difficult to remember (atleast for me), the node name management is way more difficult as well. Do anyone know how you copy a nodename database from another machine with DECnet+? Two questions: 1-May I use area 44? Sure. 2-Is there a short guide to set up DECnet over IP to connect to HECnet? Not that I know of. Maybe Mark Wickens have something on hecnet.eu? My page (http://www.update.uu.se/~bqt/hecnet.html) only have information about the bridge.

I forget what all OS's I was having issues with, I know one was RSTS/E v10.1, but I want to say it also included VAX/VMS. Once I *upgraded* my Alpha running OpenVMS to DECnet Phase IV, all these issues went away. These were things as simple as SET HOST. It's probably that DECnet-Plus (Phase V) cannot speak with DECnet Phase III (such as on RSTS/E and TOPS-10/20). That's my guess anyway. Phase V should be able to communicate with VAX/VMS since that's Phase IV, which is the gold standard of DECnet, IMHO. --Marc Geen virus gevonden in het binnenkomende-bericht.
